Description
Technical field
The utility model belongs to transmission line annex dismantling device, especially a kind of lead spacer fast assembling-disassembling device.
Background technology
Along with the development of the above superhigh pressure of China 500kV and UHV transmission line, multiple fission conductor is generally promoted, and variously also arises at the historic moment for the conductor spacer on multiple fission conductor.Conductor spacer is on multiple fission conductor, to use the attached gold utensil of maximum one, undertaking transmission line mechanical support and preventing whiplash, the inhibition aeolian vibration between wire and suppress the important function such as time span concussion, its operation conditions is related to security of operation and the useful life of transmission line multiple fission conductor.Conductor spacer is exposed in atmosphere and is subject to for a long time conductor vibration, strong mechanical stress, suddenly cold and hot, the impact of the adverse circumstances such as expose to wind and rain, there will be that wire clamp is loosening, wire clamp comes off, rubber damping pad comes off and the fault such as main body fracture, as processed not in time, conductor spacer long term wear wire will cause conductor cord disconnection, fall the major accident such as bar, brings massive losses to electric power system.
In extra high voltage network service work, opening lead spacer and checking, overhaul is one of daily task of power worker.Along with the high speed development of economic construction, power grid construction is also accelerated development, and ever-increasing extra high voltage network requires the new line construction period shorter and shorter, and working line overhauls task accordingly also to be increased the weight of thereupon.Therefore, improve the operating efficiency that in construction and operating maintenance, conductor spacer is installed and just seem particularly important.At present, national line workman installs and removes conductor spacer and still adopts traditional screw mandrel sleeve screwing type assembling and disassembling device, and this device exists problems: <1> instrument heaviness, not Portable belt work high above the ground; <2> screws the mode of tightening up and easily damages material and instrument itself; <3> complex operation, activity duration length, inefficiency; <4> is without high altitude anti-falling measure, and fail safe is low; <5> range of application is little, can not be common to sexfid wire for quadrifid wire.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of simple in structure small and exquisite, applied widely, use efficient and convenient, the efficient lead spacer fast assembling-disassembling of construction safety device, be applicable to special dismounting 500kV and above transmission line three to six lead spacer
For solving the problems of the technologies described above, the utility model by the following technical solutions: lead spacer fast assembling-disassembling device, is mainly made up of the adjusting pumping rod, pull bar, transmission arm and the lever handle that connect successively; Regulate pumping rod one end and pull bar one end to rigidly fix to be connected or spiral movable connects, the adjusting pumping rod other end has block tongue groove, has the block tongue that can locate mode overturns in block tongue groove; Along pull rod shaft to having adjusting location hole, the pull bar other end is trimming bolt, attached fine setting baffle plate on trimming bolt; Transmission arm two ends form interconnective revolute pair with the pull bar other end and lever handle head end respectively by hinges; The lever handle tail end pendant suspension ring of setting up defences.
Regulate pumping rod and pull bar spiral movable junction to be provided with hold-down nut.
Can on locate mode upset block tongue, there is stable magnet piece.
Lack the problem of the tool specially for attaching and detaching of convenience and high-efficiency for the lead spacer on 500kV and above transmission line, inventor has designed a kind of lead spacer fast assembling-disassembling device, is mainly made up of the adjusting pumping rod, pull bar, transmission arm and the lever handle that connect successively.Compared with conventional tool, this replacer is simple in structure small and exquisite, applied widely, tightens up mode by twitch, can mount and dismount quick and easy, efficiently the lead spacer on 500kV and above overhead transmission line; The anti-fall suspension ring of lever handle tail end can be avoided this instrument falling from high altitude simultaneously, have effectively ensured the safety of Contraction in Site.Application the utility model, the operation of dismantled and assembled lead spacer becomes more simply, lighter, significantly improves efficiency and operational security.
Compared with conventional tool, the utlity model has following outstanding advantages:
One,, according to the elastic force between conductor spacer rubber cushion and wire, appropriate design, reasonable material, the size of optimizing structure, solved the problem of conventional tool heaviness.
Two, utilize lever principle, adopt to twitch and tighten up mode, avoided DO-IT-YOURSELF DIY contact-making surface to wriggle and caused material damage problem, the problem that has caused screw mandrel bending to advance and retreat while also having overcome conventional tool Lengthened moment arm rotary tightening simultaneously.
Three, owing to adopting the mode of tightening up of twitching, operation easily, only need be done a little suitable extension elongation adjustment in the time of first wire clamp of dismounting, and the dismounting of remaining wire clamp does not just need to repeat to adjust.After having solved wire clamp of the every dismounting of conventional tool, all to readjust the problem of screw mandrel extension elongation, thereby significantly improve operating efficiency.
Four, tighten up mode owing to adopting to twitch, bearing does not rotate, be convenient to fix fall prevention rope to instrument, and the fail safe while improving operation, having solved conventional tool rotary tightening (sleeve, rocking handle rotation) inconvenience is the problem of fall prevention rope.
Five, adopt polytropism operational design, be applicable to three～six lead spacer in various models, various wire clamps gap, expanded the scope of application, solved the little problem of the conventional tool scope of application.
